Objective:
This study aimed to evaluate the efficacy and safety of high-frequency oscillation ventilation combined with volume guarantee (HFOV-VG) in preterm infants with acute hypoxemic respiratory failure (AHRF) after patent ductus arteriosus ligation.
Methods:
We retrospectively analyzed the clinical data of 41 preterm infants, who were ventilated for AHRF after patent ductus arteriosus ligation between January 2020 and January 2022. HFOV alone was used in 20 of the 41 infants, whereas HFOV-VG was used in the other 21 infants.
Results:
There was no statistically significant difference in the demographic information and baseline characteristics of preterm infants included in the study. The average frequency tidal volume (VThf) of the HFOV-VG group was lower than that of the HFOV group (2.6 ± 0.6 mL versus 1.9 ± 0.3 mL, P < .001). In addition, the incidence of hypocapnia and hypercapnia in infants supported with HFOV-VG was significantly lower (15 versus 8, P < .001; 12 versus 5, P < .001). Furthermore, the duration of invasive ventilation in the HFOV-VG group also was lower than in the HFOV group (3.7 ± 1.2 days versus 2.1 ± 1.0 days, P < .01).
Conclusion:
Compared with HFOV alone, HFOV-VG decreases VThf levels and reduces the incidence of hypercapnia and hypocapnia in preterm infants with acute hypoxic respiratory failure after patent ductus arteriosus ligation.
